MOTOR-FUEL.

To all whom it may concern:

Be it known that I, WALTER T. SCHREIBER, of Baltimore, in the State of Maryland, have invented a certain new and usefullmprovement in Motor-Fuel, and do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates particularly to fuels adapted to be used i internal'combustion engines generally. N p

The object of my invention is to provide an eflicient fuel for use in internal combustion engines generally, and which contains a comparatively heavy hydrocarbon, but the constituents of which are such as to enable the fuels to be utilized in the same manner as the light hydrocarbon fuels previously used for this purpose.

Another object of my invention is to provide motor fuels-containing hydrocarbons from which. the lower paraflin hydrocarbons above propane, up to and including heptane, are substantially absent.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

' For example, in carrying out myinvention, I may provide a motor fuel comprised of the following 90 to 92 parts by volume of kerosene, 8 to 10 parts by volume f sulfuric ether.

The kerosene may be any light hydrocarbon distillate having a specific gravity between 30 B. and 50 B. These are usually hydrocarbons from which the lower members of the paraflin series of hydrocarbons above propane and up-to and including heptane are substantially absent. The proportion of sulfuric ether may be varied to som ex- Specification of Letters Patent.

tent, but it is desirable to use about the proportions stated. these being substantially more than 2% of ether based on the weight of the fuel mixture.

Instead of the sulfuric ether, I may use one of a number of other volatile low-boiling constituents and which have boiling points not in excess of 505 0., such for example as acetylene, methyl ether, acetone, carbon disulfid, methane, ethane, propane.

It will be found that motor fuels made in this manner, while containing a very large percentage of comparatively heavy hydrocarbons, can, nevertheless, beused with the greatest advantage in internal combustion engines inthe same manner that light hydrocarbons have been hitherto used, and with equally advantageous results.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit thereof.

I claim:

1. A fuel consisting of 90 to 92 parts by volume of a petroleum distillate having a density between 30 B. and 50 B., and about 10-8 parts by volume of a very volatile combustible constituent.

2. A fuel consisting of 90 to 92 parts by volume of a petroleum distillate having a density between 30 B. and 50 B., and about 108 parts by volume of ethyl ether.

In testimony that I claim the foregoing I have hereunto set my hand.

WALTER T. SCHREIBER.
